Thanks to the devs. The lastest version "wazapp-11092012-0000" seems working quite good and installed smoothly. One little bug I've noticed is when inserting an emoji, it always inserted in front of the last word of the sentence. Ex.1: Type "This is a test" then insert an emoji "", the result shows "This is a test" Ex.2: Write "這是一個測試" then insert an emoji "", the result shows "這是一個測試"
